A 70-year-old man with a diagnosis of unstable angina pectoris (UAP) and arteriosclerosis obliterans (ASO) was admitted to our hospital with chest pain and intermittent claudication of both lower extremities. Coronary artery bypass grafting (CABG) was performed prior to peripheral arterial reconstruction due to UAP. He was in good condition after CABG, but he had sharp pain in both lower extremities suddenly on the 2nd postoperative day and the creatinine phosphokinase level increased to 17, 560IU/l. On the 3rd postoperative day axillo-bifemoral bypass was performed. However 5 hours after the revascularization, respiratory arrest and ventricular fibrillation occurred and he died in spite of attempted cardiopulmonary resuscitation.
